EXHAUST-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 487,137, dated November 29, 1892. Application filed August l2, 1892. Serial No. 442,871. (No model.)

To all w72 om it may concern:

Be it known that I, CHARLES W. UMHoLTz, of Bristol, in the county of Washington and State of Virginia, have invented a new and Improved Exhaust-Nozzle for Locomotives, of which the following is a full, clear, and exact description.

My invention relates to exhaust nozzles such as are shown and described in the application for Letters Patent of the United States, Serial No. 427,986, filed by me April 6, 1892, and allowed July 20, 1892.

The object of the present invention is to provide a new and improved exhaust-nozzle which is simple and durable in construction and very effective in operation.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a transverse section of the improvement as applied. Fig. 2 is a sectional side elevation of the improvement. Fig. 8 is a plan view of the same, and Fig. 4 is a sectional front View of part of the improvement.

The stand-pipe A of the locomotive is connected in the usual manner with the exhaustpassages leading from the locomotive-cylinders, and the saidstand-pipe may be single or have a division-wall, as illustrated in Fig. l.

The upper end A of the stand-pipe A is contracted and circular in form, as is plainly shown in the drawings, and in this end are held set-screws B, engaging lugs C, projecting from the lower end of the nozzles D held concentric at its lower end in the reduced end A of the stand-pipe A, so as to forln a space between the inner surface of the end A and the lower end of the nozzle D. Above the nozzle D is arranged an inverted cone E, the

axis of which is in line with the axis of the nozzle D, as shown in the drawings. The cone E is secured at its base on an arm F, mounted to slide vertically in guideways G, formed on one side ot' the stand-pipe A. The arm F is adapted to be secured in place bya boltH, passi n gthrough a vertical slot I, formed in the arm F, the said bolt screwing in the stand-pipe A with its head abutting on the outer surface of the arm F.

It is understood that the cone E serves to spread the exhaust-steam passing up through the nozzle D, so as to pass unobstructed through the stack ofthe locomotive-boiler. It is further understood that by raising and lowering thesaid cone E the spreadingis decreased or increased as the cone moves farther away fromhor nearer to the saidV nozzle D.

Having thus fiilly described my invention, I claim as new and-,desire to secure by Letters Patentl. The combination, with the stand-pipe, of the nozzle D, entering at its lower end the upper end ofthe stand-pipe and spaced therefrom, and transverse centering-screws B, passing. through the upper end of the stand-pipe and engaging the tube and holding itconcentric with the stand-pipe, substantially as described.

2. The combination, with the stand-pipe and its concentric spaced nozzle, of the vertical guideway on the outer side of the standpipe, an angular arm, the vertical member of which is mounted in or on said guideway having a longitudinal slot, a set-screw extending through the slot into the stand-pipe, and a depending inverted cone on the/transverse member of the arm with its axisin line with that of the nozzle, substantially as described.

CHARLES W. UMHOLTZ.
